Theory of relativity

1924 - Teorija relativiteta - popularno nauˇ cna skica (Theory of relativity, a popular-scientific sketch)

General audience He glorifies mathematics often and compare it to the highest men’s achievements. Part 1. Special theory of relativity, pages 6 - 45. Part 2. General theory of relativity, pages 46 -80. He discussed also relation between the general theory of relativity and cosmology. He explains that the universe

• ccupies a closed but unbounded space. As an application
• f the theory he deduced a formula of the size of the

universe which depends only on the density ρ of the matter in the universe.
